The Hartree-Fock-Bogoliubov problem with restoration of the broken symmetries before variation as it is formulated in the VAMPIR model family will be presented. The use of essentially 'complex' transformations provides a possibility to account for time-odd unnatural parity correlations as well as neutron-proton T=1 and T=0 pairing. These approaches are able to describe the structure and dynamics of the exotic nuclei near the N=Z line in the A=60-90 mass region manifesting shape coexistence and mixing as well as competition between neutron-proton and like-nucleon pairing.
